Sounds like an air leak possibly. Make sure the air filter lid is on tight and look for any cracks in the filter box and tube going to the carburetor. Look for a tight connection on the inlet and side of the carburetor and make sure the mounting bolts on the intake manifold are snug. I'd start with that.

Is the complete air cleaner in place with good filter? If not you now know why it won't run.
